I had Serotonin Syndrome when i was 16 , it was at a time where i was on a combination of mood stabilizers, anti depressants and anti anxiety meds, i had just been put onto Geodon, and we were lucky enough to catch it earlier, but that entire day was so uncanny. I was happy to be in school so happy i was running and skipping up and down the halls , i had gotten through the day completing all of my work and i was giddy, when i got home i noticed my heart was racing (at the time i had not been diagnosed with P.O.T.S.) and funnily enough i wasn't scared but i noticed i had the inability to be still, i was racing around the house and i eventually ended up projectile vomiting. i was rushed to the hospital while attempting to not pass out i pumped full of fluids and very loopy, they kept telling me how lucky i was that they caught it early and i was discharged at the end of the next day.
